FRANCIS A. XVALSH, OF MILVAUKEE, VISCONSIN.
SHEET-METAL-SHEARING MACHINE.
SPECIFICATION forming part ,of Letters Patent N 0. 68,586, dated February 9, 1892.
Original application filed April 28, 1889, Serial No. 308,317. Divided and this application filed September 29, 1890. Serial Ho. 366,478. (No model.)
To aZZ whom it may concern:
Be it known that I, FRANCIS A. WALSH, a citizen of the United States, and aresident of Milwaukee, in the county of Milwaukee, and in the State of lVisconsin, have invented cer tain new and useful Improvements in Sheet- MetalShearing and Slitting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof.
The present application is a division of the one filed April 23, 1889, Serial 'No. 308,317, on which Patent No. 445,738 issued February 3, 1891; and the invention consists in certain peculiarities of construction and combination of parts to be hereinafter described with reference to the accompanying drawings, and sub sequently claimed.
In the drawings, Figure 1 represents a rear View, partly in transverse section, of a sheetmetal cutting and folding machine constructed according to my invention; Fig. 2, a vertical longitudinal section of the same, and Fig. 3 a plan View, partly in horizontal section.
Referring by letter to the drawings, Ajrepresents the bed-piece of a machine for squaring or slitting sheet metal, this bed-piece being provided with an adjustable gage-plate B, as illustrated in Figs. 2 and 3. Extended upward from the front corners of the bedpiece A are slotted standards C, that serve as guides for lateral projections b on the sliding frame D, the latter being provided with links 0 for connection with the treadle or other operating mechanism, (not shown,) and said lateral projections of the sliding frame are connected by spiral springs E with parallel projections d on the upper ends of the standards, as best illustrated in Fig. 2, these springs serving to automatically return said sliding frame to its normal position after being drawn down by the treadle or other aetuatingmechanism. By means of set-screws c a shearblade F is secured to the sliding frame D at the proper angle, and an opposing sheanblade G is secured to the bed-piece A by means of set-screws f, the parts thus far described be ing similar in construction and arrangement to sheet-metal-shearing machines as ordinarily constructed.
In the present machine plates 11, having their lower edges in the form of dies g, are secured to the sliding frame I) in rearof the shear-blade F, these die-shaped edges of said plates being on a horizontal lineat all points above the cuttingedge of said shear-blade. In order that one or all of the die-plates H may be raised or lowered, Iprovide them with vertical slot-s h, and connect them w ith the sliding frame D by means of set-screws '5, passed through said slots. 'lhedie plate or plates H being raised up, they are out of the way when those edges of the sheets not to be'folded are being trimmed, and this same result may be attained by having said plate or plates on a hinge, so as to be swung out of the way at the will of the operator.
lVhile I have shown two die-plates, either one or both of which may be adjusted independent of the other, it is obvious that a greater number of such plates may be employed, or that a single plate equal in length to all of the separate plates may be substituted, this being a matter of convenience or necessity as practice may determine.
The usual ledge j on the front of the. bedpiece A for the support of the lower shearblade G is sufficiently extended to also support a plate I, the upper edge of the latter and said blade forming a die it, arranged to oppose the die on the plate or plates H, carried 011 the sliding frame D, as above described, said lower dieplate being in rear of said lower shear-blade and held therewith against said bed-piece by means of the set-screws f, as best illustrated in Fig. 2.
The dies g 7.: may be of any desirable form; but, asshown, they are preferably edge-foldin g dies, similar to those described in the previous application above named, or, in other words, each die has one face thereof normally at right angles to the sheet to be operated upon and another face beveled in a direction acute to the plane of said sheet, the latter being free to incline toward the non-beveled faces of said dies when the engagement of the latter takes place, whereby a fold is formed parallel to said non-beveledfaces of the dies and at an acute angle to the body of the aforesaid sheet.
In the operation of the machine herein described a sheet to be operated upon is held on the bed-piece A against the gage-plate B and the sliding frame D drawn down to effeet the shearing operation, the latter being immediatelyfollowed by an engagement of the edge-folding dies g 70 against the sheet, after which said sliding frame is automatically returned to its normal position by means of the springs above described.
While I have shown the dies in connection with a machine having a sliding frame carrying one of the blades, said dies may be as readily employed in similar machines in which a rotary cutter or cutters are employed.
Having thus described my invention, what I claim asnew, and desire to secure by Letters Patent, is
1. In a machine for squaring or slitting metal sheets, the combination, with the shearing mechanism, of edge-folding dies adapted to form an acute-angled fold in the stock approximately to and along the line of the cut, substantially as set forth.
2. In a machine for squaring or slitting metal sheets, the combination, with the shearing mechanism, of edge-folding dies, each die having a face normally at right angles to the sheet being operated upon and another face beveled in a direction acute to the plane of with to fold the edges of the sheets, and suitable means for adjusting one of the dies, substantially as set forth. I
4. In a machine for squaring or slitting metal sheets, the combination, with the shearing mechanism, of a pairof dies, one of which is in sections, and suitable means for adjusting each of the die-sections, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Visconsin, in the presence of two witnesses.
FRANCIS A. WVALSII.
